The language of music is universal, but to master it and understand how sounds interact, you need to know its foundations. The Music Dictionary is the starting point for students, musicians and curious people who want to learn music theory from the most basic ideas up.
Recommended learning path
To study from scratch, follow this order. Each concept has its own guide, with staff examples you can listen to.
| Step | Concept | Why it matters |
|---|---|---|
| 1 | Staff and clefs | Without reading the staff, you cannot move forward in any other area. |
| 2 | Musical notes | The name and position of the 7 notes and their accidentals. |
| 3 | Time signatures | How time and rhythm are organized in music. |
| 4 | Whole steps and half steps | The basic units of distance between notes. |
| 5 | Musical intervals | Measuring the distance between two notes: number and quality. |
| 6 | Major scales and minor scales | The 7 degrees of a key and their key signatures. |
| 7 | Triads | The four types of three-note chord and their inversions. |
| 8 | Closely related keys and scale degrees | The basis of modulation and harmonic analysis. |
Concepts
Qualities of Sound
Pitch, duration, intensity and timbre: the four properties of musical sound.
Dynamics
Dynamic marks (pp, mf, ff), crescendo and diminuendo hairpins, and sudden changes.
Tempo
Tempo markings (Largo, Andante, Allegro…), their BPM and changes of speed.
Articulation
How each note is attacked and connected: legato, staccato, accent, tenuto and marcato.
Expression Markings
Dolce, cantabile, espressivo, maestoso, con brio… the character of the music and what each term means.
Performance Effects
Techniques that change how a note sounds and connects: glissando, portamento, arpeggiation, vibrato and tremolo.
The Staff
Lines, spaces, treble clef and bass clef. The foundation of music writing.
Note Names
Letters and solfège names, pitch and their place on the staff.
Note Values
Whole note, half note, quarter note, eighth note… the length of notes and rests.
Repeat Signs
Repeat bars, first and second endings, D.C., D.S., coda and fine. With examples you can hear.
Ornaments
Appoggiatura, mordent, turn and trill: how they are written and how they sound, with audio.
Clefs
Treble, bass and C clefs. How to read notes in each clef.
Octave Numbering
Numbering the octaves: the international system (C4) and the French-Belgian system (C3).
Notes on Instruments
Where each note is on each instrument: the keyboard, the fingerboard, the fingerings… The same note, a different shape.
Accidentals
Sharp, flat and natural: how the pitch of notes is raised and lowered.
Time Signatures
Duple, triple, quadruple. Beat, strong beat and subdivision.
Intervals
The distance between two notes. Classification, inversion and harmonic use.
Chords
Triads, seventh chords, inversions and basic harmonic functions.
Keys and Scales
Major and minor scales, key signatures and the circle of fifths.
Scale Degrees
Names and functions of the seven degrees: tonic, dominant, leading tone and more.
Cadences
Authentic (perfect and imperfect), plagal, deceptive and half cadences, with examples.
Harmonic Functions
Tonic, subdominant and dominant: what each chord does within the key.
Modulation
Changing key: pivot chord, diatonic, chromatic and enharmonic modulation.
The Musical Phrase
Motive, semi-phrase, phrase and period; beginnings (downbeat, pickup, off-beat) and endings.
Frequently Asked Questions
What is a music dictionary?
A music dictionary is a collection of music theory terms and concepts with definitions and explanations. It covers ideas such as intervals, chords, scales, keys, time signatures, clefs and scale degrees, with practical staff examples to make them easier to understand.
In what order should the basics of music theory be learned?
The recommended order is: first the staff and clefs (so you can read notes), then the names and pitch of the notes, then time signatures (to understand rhythm), intervals (the distance between notes), keys and scales, and finally chords and their harmonic functions.
Why study music theory?
Studying music theory lets you read scores, understand how songs are built, talk with other musicians in a common language, improvise with purpose and prepare for conservatory exams. It is the foundation for any instrument and for composing.
How many concepts does this music dictionary include?
The dictionary covers dozens of music theory concepts, from the staff, note names, clefs, time signatures, intervals, chords and keys to cadences, harmonic functions and modulation. Each page includes definitions, tables and examples with staff images.
Can you study music theory without playing an instrument?
Yes. Music theory can be studied purely as theory. However, practicing it on an instrument speeds up understanding: hearing the concepts, such as an interval of a third or a major chord, fixes the knowledge much better than just reading about it.
